INVENTOR ATTORNEYS CHARLES W. HILL, OF PEORIA, ILLINOIS.

EXCAVATOR-BUCKET CLEANER.

To all whom it may concern: V

Be it known that 1, CHARLES W. HILL, a

citizen of the United States, and a resident of Peoria, in the county of Peoria and State of Illino1s, have invented a new and Improved EXcavator-Bucket Cleaner, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a power digging shovel with a shedding surface; to provide asurface of the character mentioned automatically operative; and to provide a surface the construction and arrangement whereof is simple and readily removed for repair or replacement.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of a fragment of the digger boom having provided thereon a shovel of the character mentioned, showing in conjunction therewith a cleaner surface constructed and arranged in accordance with the present invention; Fig. 2 is a detail view, on an enlarged scale, of a cleaner constructed and arranged in accordance with the present invention, the overlaid plates of which the cleaner is con structed being shown in normal position; Fig. 3 is a similar view, showing the plates in the contracted or shedding position; Fig. 4: is an edge view of the same; Fig. 5 is a side view of the frame for supporting the shedding plates, said plates being removed; and Fig. 6 is a cross section taken on the line 6-6 in Fig. 2. In the accompanying drawings, and in Fig. 1 thereof, is shown a shovel A of the character mentioned. The shovel is suitably secured to a boom B by means of a bolting flange C. The connection is reinforced or braced by the rods D. The shovel of the character shown is provided with an opening bottom E hinged at F. The bottom is locked in closed position by means of a strap bolt latch G which is operated by means of a chain H when connected to the lever to which is operatively connected the jerk line J. The construction and operation of the parts above pointed out are those usually Specification of Letters Patent.

In the present disclosure the cleaning surface constructed and arranged in accordance with the present invention is disposed between the prolongation of the body portions of the teeth K. The body portions L are spaced apart, as shown particularly in Fig. 10f the drawings, and are properly armored on the exposed surface to avoid the wear of the material being handled. Between the body portions are suitably mounted overlaid plates 11 and 12.

The construction of the plates 11 and 12 and of the mechanism for operating the same are best shown in Figs. 2 to 6 inclusive of the drawings. The plates 11 and 12 are each provided with bolts 15;) and 14;. The bolts 13 and 11, extend through slots 15 formed in plates 16 and 17. The plate 16 is rigidly connected with the frame 18 while the plate '17 is loosely mounted on the said frame.v The frame 18 is connected and reinforced by a plate 19 extended between the sides of the frame 18 about midway of the structure, and also by an end plate 20 and a cross bar 21. The plate 20 is provided with a wedge surface 22 to fend the material when entering on the plates 11 and 12 and carry the same over the ends of the said plates. j

The purpose in the construction whereby the plate 17 is loosely mounted on the frame is to admit of adjusting the base plates 16 and 17 to the space between the body portion L of the teeth K in various makes of shovels. To guide the shifting plate 17 it is provided with bolts 23 which are slidably mounted in slots 24 formed in the rein forcing plate 19 and'the end plate 20, as shown best in Fig. .5 of the drawings. It is to retain the plate 17 in fixed position that the same is further provided with a loose pin 25 adapted for insertion within the perforations 26 formed inthe reinforcing plate 19, as shown in Figs.5 and 6. The disposition of the plate 17 is manually performed, the plate being shifted, and when adjusted being locked firmly in position. For this purpose, where it is desired, the pin 25 is provided wit-h a screw threaded section and a nut to hold the same. This construction is' not shown in the drawings, asforming no essential part of the invention.

Thebolts 13 which hold the sliding plates 11 and 12 are provided with any suitable means of retaining them in the slots 15, such as washers, nuts or suitable pins. The bolts 14 are pivotally connected with link arms 27. The arms 27 are pivotally connected with a head block 28, which head block has fixedly mounted therein a bunter rod 29. The rod 29 is guided by the loops 30 which are fixedly mounted on a plate 31. The frame 18 is fixedly mounted in the space between the body portions L of the teeth K by bolts driven through perforations 32 at the lower end of the said frame.

As shown in Fig. 6 of the drawings the plate 11 is overlaid upon the plate 12. The weight of the plates when mounted in the vertical position shown in Fig. 1 of the drawings it will be seen rests upon the bolts 13 and 14. The bolts 13 and 14 being disposed in the slots 15 and loosely held therein, slide within the said slots to the lower end thereof, when the hunter rod 29 is released by the bottom E of the shovel A. This is the position shown in Figs. 3 and 5 of the drawings, and this is the position assumed by the plates 11 and 12 when the shovel is open to deliver its contents.

As seen in Fig. 3 the plate 12 has practically disappeared under the plate 11. When the bottom E is closed it swings against the bunter rods 29 of each of the various cleaner surface sections, lifting the said bunter rods and the link arms connected therewith and the plates 11 and 12. The plates 11 and 12 being thus lifted are guided by the bolts 13 and 14 to expand laterally to fill the entire space between the body portions L of the teeth K.

It is in the last mentioned position of the preceding paragraph that the shovel A is operated to dig. It will be seen that as the load is separated from the embankment it is carried over the inclined surface 22 between the body portions L of the teeth K and rests against the outspread plates 11 and 12. It is to avoid the usual adhesions, as when digging into sticky clay, that the plates 11 and 12 are provided to shed the load and avoid the necessary pounding and wedging usual in the handling of shovels of this description.

The load having been received by the shovel, the boom is swung to the point of delivery, when by manipulating the jerk line J the bottom E is allowed to swing down ward to dump the contents from the shovel A. As the load is thus dropped it will be noticed that the bottom E is removed from the hunter rods 29, thus permitting the said rods and the plates 11 and 12 connected therewith to drop until the bolts 13 and 14 are at the lower end of the slots 15. It will also be noticed in this connection that the drop of the plates 11 and 12 is in part actuated by the load, provided the same adheres thereto. During the drop of the plates 11 and 12, however, by reason of the connection between the bolts 13 and 14 and the slots 15, the said plates are converged or moved toward the center of the space occupied thereby, severing any adhesions to the plate 11 by the movement thereof, and the plate 11 serving to scrape the material from the surface of the plate 12. This rapid movement of the parts forming the surface between the body portions L of the teeth K serves to shed the material effectually from this portion of the shovel A.

lVhile I have herein described and shown the invention as applied to a bucket having digging teeth, it will be understood the same is equally applicable to buckets having a straight edge.

It will also be understood that the details and arrangement of the same shown and described may be varied without altering the present invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1.
